Laser Spirograph

This laser spirograph is constructed from a 5v red laser module, 2 DC motors salvaged from printers, mirrors cut from hard driver platters, 3d printed mounts, and an Arduino Pro Mini which varies the speed of the two motors using PWM and random sinusoidal waveforms. The case is laser cut from 1/8″ birch plywood.
